Solar flaring activity over the past 24 hours was at very low levels (below C-class flaring). At present there are only two numbered active regions on the visible solar disc. NOAA 3062 and NOAA 3066 have now rotated behind the west limb and the neighbouring region NOAA 3069 has decayed into plage. NOAA 3068 (beta-gamma) remains the largest active region and has slightly grown and increased its magnetic complexity. Despite that it has not shown any significant flaring activity. A small active region in the north-eastern quadrant was numbered as NOAA 3070 and classified as magnetic type beta. It has been inactive and stable, as well as the newly rotated active region near the south-east limb. The flaring activity over the next 24 hours is expected to be at predominantly at very low levels with possible C-class flaring.

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux has been below the1000 pfu threshold and is expected to remain below the threshold in the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so over the next 24 hours.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) was under the mild influence of a high speed stream (HSS) originating from a high- latitude extension of the negative polarity southern polar coronal hole. The solar wind velocity varied between 430 km/s and 530 km/s. The interplanetary magnetic field was weak to moderate with a maximum value of 8.4 nT and the Bz component barely reached -7 nT. The B field remained in the negative sector (directed towards the Sun). The solar wind parameters are expected to remain slightly enhanced over the next 24 hours under the influence of the HSS. A faint small positive polarity coronal hole has crossed the central meridian in the northern hemisphere and might cause additional enhancements in the near-Earth solar wind conditions late on Aug 4th.

The geomagnetic conditions over the past 24 hours were quiet to unsettled. Quiet to unsettled geomagnetic conditions are expected over the next 24 hours in response to the ongoing HSS. Isolated active periods remain possible, but unlikely.
